piping engineers!

a dear friend sent me a cut out he read from a forum regarding piping engineers: 

"Isn't the job called plumber? My uncle is a plumber and he works basically the whole week. I never heard him call himself with a glamour name piping engineer. Haha.

If he got calls then he drives to the house location with his Indon worker. Must be willing to get your hands dirty and most times sweaty (because no fan or aircond). Offdays are decided by himself. Graduate or no graduate will bear no difference in your pay because the homeowners want to get their piping fixed or installed that's all. He bought himself a Toyota Altis recently- must be good pay but like I said, hard work. In terms of progression, you get more contacts and people can recommend you more job. Then start to take in some foreign worker to help you out."

LOL!
